Specification of Letters Patent.

Patented Mar. 1, 1910.

Application filed June 23, 1908, Serial No. 440,009. Renewed. August 10,1909. Serial No. 512,251.

To all whom it may concern:

Be it known that I, JosnrI-r PRASKA, a citizen of the United States,residing at Conway, in the county of iValsh and State of North Dakota,have invented certain new and useful Improvements in Twine-FeedingDevices for Grain-Binders, of which the following is a specification.

This invention relates to the class of harvesters, and more particularlyto grain binders, and has for an object to provide a twine feedingdevice which may be conveniently applied to binders of ordinaryconstruction, and which will effectively serve to govern the output oftwine when the device is in use.

A further object of this invention is to provide a device of the abovedescribed character whereby the twine will be held taut between thebundle tying mechanism and the twine holding receptacle, and to providemeans for engagement with the twine, whereby it will yield should themechanism of the binder become temporarily inoperative.

Other objects and advantages will be apparent from the followingdescription and it will be understood that changes in the specificstructure shown and described may be made within the scope of the claimswithout departing from the spirit of the invention.

In the drawin s forming a portion of this specification, and in whichlike numerals of reference indicate'similar parts in the several views,Figure 1 is a side elevational view of the present invention. Fig. 2 isan end view. Fig. 3 is a longitudinal sectional view. Fig. 1 is a topplan view.

Referring now more particularly to the drawings, there is shown a twinecontainer 5 for grain binders, the same being in the form of areceptacle, but it will of course be understood that any suitablecontainer or.

holder for the twine may be employed. The receptacle is mounted in anysuitable manner to a binder as shown at 6 in the drawings, and ispreferably located adjacent to the bundle tying mechanism of the bindernot shown.

The binder is provided with a twine feeding device 7 consisting of aplate 8 secured to the binder by means of bolts or similar fasteningdevices 9 and which is preferably located adjacent to the twinereceptacle previously described. The plate 8 is provided with spacedflanges 10 and 11 respectively at its sides, and at the center, theplate is provided with spaced brackets 12. The brackets 12, adjacent totheir outer ends receive a shaft 13 which carries a loosely mountedcorrugated roller lat.

At each side of the brackets 12, the plate is provided with an arm 15each having a reduced portion 16 at its lower end disposed between theflanges 10 and 11 respectively of the plate and which receives a pin 17where by the arm is pivotally mounted for a purpose to be hereinafterdescribed. Each arm is provided at its upper end with spaced cars 18which are directed toward the roller 14!: and which receive the ends ofa shaft 15.) which thus supports a corrugated roller 20 similar to theroller 1%, as shown. It will thus be seen that the teeth 21 of each ofthe rollers 20 are thus arranged for movement between the teeth 22 ofthe roller 14:.

Each arm 15 is provided adjacent to its lower end and above its pivotpin 17 with an elongated passage 23, and disposed in these passagesthere is shown a longitudinally extending rod 24 having its endsdisposed outwardly of the passages formed in the arms 15. The rod isprovided with washers 25 arranged to bear upon the outer faces of thearms 15 and against which the inner ends of coil springs 26 are disposedwhich are carried by the rod 2&. The ends of the rod 2-1 are threaded asshown at 27 and thus receive adjusting nuts 28 whereby the tension ofthe springs may be varied to govern the pressure of the rollers 20against the roller 14, as will be readily understood.

Each arm 15 is provided adjacent to its roller 20 with a passage 29arranged to re ceive the twine A from the receptacle previously referredto. It will thus be seen that the twine may be threaded through thepassages 29 and wound between the rollers 20 and over the roller 14:. Itwill of course be understood that the free end of the twine is connectedwith the tying mechanism of the binder. Should the tying mechanism ofthe binder become temporarily inoperative, or should the twine containedin the receptacle become knotted or tangled it is obvious that the twinebetween the receptacle and the tying mechanism will yield suiiicientlyto prevent breakage thereto.

The plate 6 is provided with a bearing bracket 6 for the reception ofthe rod, and this bracket is provided with a set screw or the like forengagement with the rod whereby it is held against sliding movement. Itwill thus be seen that the springs 26 may be used separately or inconjunction with each other at the will of the operator.

The roller 14 at one end is provided with an annular smooth face 14*against which a leaf spring 14 frietionally bears, which is :arried byone of the brackets 12, and thus acts as a brake, as will be understood,and to vary the tension of the spring, I provide a set screw 1%".

hat is claimed is.

l. A twine tension device for grain binders comprising a bracket, acorrugated roller revolubly mounted inthe bracket, pivoted arms locatedat opposite sides of the bracket, a corrugated roller mounted in each ofthe pivoted arms, said arms being movable upon their pivots to bringtheir rollers into and out of inter-meshing engagement with the firstnamed roller, and means for holding the pivoted arms yieldably withtheir rollers in engagement with the first named roller.

2. A twine tension device for grain binders comprising a stationarybracket, a rev- I I I I oluble corrugated roller carried by saidbracket, swinging arms located adjacent to said bracket, a rollercarried by each of said swinging arms, and spring means engaged withsaid swinging arms for holding their rollers yieldingly engaged with thefirst named roller.

3. A twine tension device for grain binders comprising a stationarybracket, a revoluble roller carried by said bracket, swingings armslocated adjacent to said bracket, rollers carried by said swinging armsfor engagement with the roller carried by said bracket, said swingingarms having passages, a rod having threaded ends disposed in saidpassages, adjustable nuts carried by said rod, and springs carried bysaid rods and disposed between said swinging arms and said nutsrespectively.

In testimony whereof I aflix my signature, in presence of two witnesses.
